Tracking sea bed topography in the Jurassic. The Lotena Group in the Sierra de la Vaca Muerta (Neuquén Basin, Argentina)
(Universitat de Barcelona. Facultat de Geologia, 2005-12)
The Lotena Group is a clastic to evaporitic unit up to 650 m thick that accumulated during the Middle to Late Jurassic in the Neuquén Basin, western Argentina. Extensive field work carried out in the Sierra de la Vaca ...
The Chachil Limestone (Pliensbachianeearliest Toarcian) Neuquén Basin, Argentina: UePb age calibration and its significance on the Early Jurassic evolution of southwestern Gondwana
(Pergamon-elsevier Science Ltd, 2013-06)
New radiometric UePb ages obtained on zircon crystals from Early Jurassic ash layers found within beds of the Chachil Limestone at its type locality in the Chachil depocentre (southern Neuquén Basin) confirm a Pliensbachian ...
Palynotaphofacies analysis applied to Jurassic marine deposits, Neuquén Basin, Argentina
(Springer, 2016-04)
Taphonomic analysis was performed on palynological samples of marine successions from the Cuyo Group of the Neuquén Basin. The group comprises the Los Molles and Lajas Formations (Middle Jurassic) and represents the first ...

(Asociación Paleontológica Argentina, 2016-12)
El Mesozoico constituye un momento crucial para analizar el recambio de los distintos linajes microplanctónicos producto del inicio de la ruptura de Pangea. La paleogeografía de Sudamérica y por lo tanto la de Argentina, ...
New contributions to the palaeoenvironmental framework of the Los Molles Formation (Early-to-Middle Jurassic), Neuquén Basin, based on palynological data
(Springer, 2020-10-12)
Being the main oil-bearing basin of Argentina, the Neuquén Basin contains a well-documented stratigraphic record of continental and marine sedimentation during the Jurassic and Cretaceous in the western margin of Gondwana. ...
Anatomy and Sequence Architecture of the early Post-Rift in the Neuquén Basin (Argentina): A Response to Physiography and Relative Sea-level Changes
(Society for Sedimentary Geology, 2013-08)
A detailed architectural and sequence stratigraphic analysis was carried out in the early-post-rift succession of central Neuque´n Basin (Middle Jurassic Cuyo Group), integrating outcrop and subsurface information from a ...
Amonites y bioestratigrafía del Grupo Cuyo en la Sierra de Reyes (Cuenca Neuquina central, Argentina) y su significado secuencialAmmonites and biostratigraphy of the Cuyo Group in the Sierra de Reyes (central Neuquén Basin, Argentina) and their sequential significance
(Servicio Nacional de Geología y Minería, 2012-09)
This paper deals with the stratigraphy, the systematics of the ammonite faunas and the biostratigraphy of the Cuyo Group in the Sierra de Reyes (southern Mendoza Province, Argentina). The 230 m-thick marine siliciclastic ...
